The "*" in the table ID indicates that the JST date of the upload is different from the UT date of Pass 1. This table plan is likely to change. Prepare for last minute changes. Continuing requests: KSC & SSOC Tohbans: If any KSC passes are likely to be cancelled (for example due to typhoons) or an SXT table cannot be uploaded for any reason, please telephone and e-mail the Chief Observer immediately. (sxt_co@isass0.solar.isas.ac.jp, copy to sxt_st@flare2.solar.isas.ac.jp). KSC Tohbans: In general flare mode supersedes table upload, i.e. if a flare is in progress please do not upload a new table, and contact the chief observer. Normally it is OK to go ahead with the planned table without change on the next pass, if it is available. Chief observers should keep an eye on this.
